Frequently Asked Questions

What should I include in a professional estimate?

A professional estimate should include your business name and contact information, the client's details, a unique estimate number, an itemized list of services or products with quantities and prices, applicable taxes and discounts, the total cost, payment terms, and a validity period. Including a clear scope of work helps prevent misunderstandings later.

What is the difference between an estimate and a quote?

An estimate is an approximation of costs that may change as the project progresses, while a quote is a fixed price commitment that you are obligated to honor within a specified timeframe. Estimates are better for complex projects where scope may evolve, and quotes work well for standardized or clearly defined services.

How long should an estimate be valid?

Most business estimates are valid for 30 days, though this varies by industry and project size. For projects with volatile material costs or tight resource availability, 14 days is common. Longer validity periods (60-90 days) may be appropriate for large enterprise projects that require internal approval processes. Always state the expiration date clearly.

How do I properly itemize an estimate?

Break your estimate into logical categories or project phases, with each line item showing a clear description, quantity or hours, unit price, and line total. Group related items together and include subtotals for each section. This level of detail builds client trust and makes it easier to negotiate specific elements without reworking the entire estimate.

What is the difference between an estimate and an invoice?

An estimate is sent before work begins to outline expected costs and scope, while an invoice is sent after work is completed (or at billing milestones) to request payment. An estimate is not a legally binding payment request, but an invoice is. Many businesses convert approved estimates directly into invoices once the work is done.

Should I include terms and conditions on my estimate?

Yes, including basic terms and conditions protects both you and your client. At minimum, cover payment terms, what happens with scope changes, cancellation policies, and intellectual property ownership. Keep them concise and easy to understand -- lengthy legal jargon can intimidate clients and slow down the approval process.
